First, make sure you have your Nero 6 serial number so you can reinstall Nero/NeroExpress after using CleanTool. The serial number should look like this: 1A2x -xxxx-xxxx-xxxx-xxxx-xxxx. The serial number should be located on the inside of the Nero jewel case, or on the back of the paper sleeve the Nero CD came in. You can also open Regedit (a program in C:\Windows), and go to “HKEY_LOCAL_MACHINE \ SOFTWARE \ Ahead \ Nero-Burning Rom \ Info” to obtain your Nero 6 serial key from there.
Next, download Nero CleanTool to your desktop. Unzip the file with WinZip or WinRar and then double-click on the EXE file to run it. Reboot your system when CleanTool has finished - this will clean the registry and remove all Nero entries. After that, download and install the latest Nero 6 version from our webpage.
Enter your Nero 6 serial number to unlock the trial version.
